turboquant-rs 0.3.1

//! Compressed KV-cache implementations for LLM inference.
//!
//! This module provides [`PqoCache`] (PolarQuant, covering both PQ and PQO
//! modes via `CacheConfig::outlier_blocks`) and [`TqCache`] (TurboQuant with
//! QJL correction).
//!
//! All implementations use the [`CompressedKVCache`] trait from
//! `mistralrs-kv-cache`, making them drop-in replacements for any
//! inference engine that supports the trait.
//!
//! Requires the `candle` feature flag.
